VdS 3188

VdS 3188 – VdS Guidelines for Planning and

Installation:

Water Mist-Sprinkler and Water Mist Fire

Extinguishing Systems

Same systematic as VdS CEA 4001

For specific applications: Water Mist is regarded equal to

Sprinkler, Deluge or Gas Exinguishing Systems

VdS 3188 will include CEN TS 14972
